摘要

Due to the existence of old mortar on the surface of recycled aggregate, the physical properties of recycled aggregates are inferior to those of natural coarse aggregate. This can results in large discreteness of mechanical and durability properties of recycled concrete, which is lower than that of ordinary concrete. In order to improve the mechanics and durability of recycled concrete, scholars have done a lot of research on the modification and strengthening of recycled aggregate. This paper mainly summarized the modification and strengthening methods of recycled aggregate. And the effects of different modification methods on the physical properties of recycled aggregate and the physical and mechanical properties of recycled concrete were discussed.
